A comic book industry event: a new original ongoing superhero series from Mark Waid! IRREDEEMABLE dares to ask the question: what if the world's greatest hero decided to become the world's greatest villain? Does Plutonion’s past hold the key to his current deadly rampage? Or does it even matter? A "twilight of the superheroes"-style story that examines super-villains from the writer of KINGDOM COME and EMPIRE!
